Post your breakthrough sig

I took this idea from GSA which was the biggest GFX site of it's era, where I was a Jr. Admin, had about 300+ replies.
This is a thread where you basically just post the sig where you think that your revolution of good GFX started.
The sig that you tried new things and styles and got great feedback.
Don't spam too much.
I'll post mine when I get some time to find it.
